Abstract (en)

The present invention provides a heat mode recording material comprising on a side of a support having an oleophilic surface (i) a recording layer containing a light-to-heat converting substance capable of converting radiation into heat and (ii) an oleophobic surface layer, wherein said oleophobic surface layer and said recording layer may be the same layer and on another side of the support a backing layer, characterized in that the maximum roughness depth Rt of the surface layer is at least 0.65 mu m and/or the maximum roughness depth of the outer back layer is at least 1.20 mu m.
